Abstract: ABSTRACT OF THE DISCLOSURE      Herein disclosed is a valve actuating mecha-nism having a stopping function for use in an internal combustion engine of the type, in which at least one pair of intake or exhaust valves having an identical function and disposed adjacent to each other are arranged for one cylinder.  First and second rocker arms respectively having arms abutting against the upper ends of the paired intake or ex-haust valves are rockingly supported on a common support shaft which is fixed on the engine body while having an axis perpendicular to the operating directions of the valves.  The first rocker arm is formed with a cylinder bore which is opened toward the second rocker arm to bear a plunger therein whereas the second rocker arm is formed with a guide bore which is opened toward the first rocker arm to fit the plunger therein.  A hydraulic actua-tion chamber defined between the bottom portion of the cylinder bore and the rear end of the plunger is connected with an oil-pressure source through a hydraulic change-over valve for changing the supply and stop of the oil pressure to the actuation chamber.  Either of the first or second rocker arm is formed with a cam slipper for sliding contact with a cam which is adapted to rotate in accordance with the run of the engine.

Abstract: "EVAPORATION DEHYDRATOR"                     ABSTRACT OF THE DISCLOSURE           A method and apparatus for the treatment of oilfield heavy oil emulsions is provided.  The method utilizes, in combination, the steps of evaporation, vapor/liquid separation, and solids settling to dehydrate, degassify and remove solids from the heavy oil emulsion and produce oil having less than .5% by volume basic solids and water. The apparatus comprises an insulated, horizontal, cylindrical vessel.  Mounted in the upper end of the vessel chamber is an inclined, tubular member having a closed upper end and an open lower end.  At its closed end, the member forms a receiving chamber.  A mechanical foam breaker extends transversely across the interior of the tubular member, down-stream of the chamber.  A stack of angularly inclined, heated trays, arranged in zigzag fashion, are positioned beneath the tubular member, to provide an elongate flowpath.  The lower end of the tubular member is positioned to feed onto the upper end of the first tray.  The flowpath formed by the stack of trays terminates at a level above the bottom of the vessel, so that a quiescent settling sump is provided by the base of the vessel.  The vessel includes a feed inlet opening into the receiving chamber, a vapour outlet leading from the top of said vessel, and liquid and solids outlets leading from the sump.           A stream of pre-heated heavy oil emulsion is fed to the receiving chamber, wherein part of the contained water in the vapour form breaks out.  The foaming stream is contained by the tubular member and is substantially disintegrated by the foam breaker.  The stream then issues onto the upper end of the stack of trays and is heated as it passes as a shallow, broad layer over the trays, to gradually evaporate the remaining water from the emulsion and solids.  The dehydrated solids are settled out in the sump, leaving oil containing less than 0.5% basic solids and water.

Abstract: PHA 1110                         12                        22.05.1985 ABSTRACT: Phase detector and PLL circuit comprising such phase detector.         Phase locked loop (PLL) circuits are widely used for data carrier extraction in many applications. Conventional PLL's have the disadvantage that the VCO oscillating frequency will be driven to its minimal or maximal frequency when the input data signal is absent and therefore the locking to a new data signal takes a relatively long time. This is unacceptable in applications where the input data signal often is interrupted and a fast locking is required (e.g. PLL circuits in disk controllers). The invention presents a new PLL circuit and a new phase detector for preventing the long lock acquisition times by controlling the VCO by a predetermined reference frequency when the data input signal is absent.

Abstract: ABSTRACT          Improvements in Centrifugal Couplings.          A coupling (10) has input (16) and output (18) members interconnected by two-link (2,3) coupling elements (A,B,C) which are flexible in the plane of rotation by centrifugal force acting on them as the coupling (10) rotates and by the torque transmitted.  The coupling is soft over a range of speeds and torques.            The input member (16) is constructed from two metal spinnings (28,30) welded together to form a housing which supports the pivot (X) of each coupling element at both ends.  Thus the input member is much lighter.  The output member (18) is similarly constructed with bushes (47a,b) welded on to support the pivot (Y) also at both ends.  The output member is thus lighter and less complicated to make. The pivots (J,Y) are axially free within limits increasing the axial misalignment capability of the coupling (10).  A spring arrangement to buffer the links (2,3) if they rapidly approach their stops is provided.
